Lunar eclipses occur when our planet slides between the sun and moon, which temporarily prevents the sun’s light from falling on the lunar surface. A total lunar eclipse is the most dramatic, and is often referred to as a blood moon.

Stargazers across Australia will stay up late this Tuesday as the full moon turns red in a rare, "must-see" lunar eclipse. On Tuesday night, the moon will slowly slip into Earth's shadow and emerge glowing deep red in a total lunar eclipse — the only 'blood moon' visible from Australia in 2026.

Tonight, the sky may put on one of its rarest shows: a total lunar eclipse blood moon and possible Selenelion.
